DeflatingtheBCthroughtheMouthpiece
• Hold the lower (power) inflator higher than the top of BC and depress the inflate/deflate button
on the end of the Inflator to release the air.
• The mouthpiece must be higher than the BC to ensure complete deflation of the BC.
• While underwater, you will hear the air bubble out through the mouthpiece when you depress the
button. Be sure to release the button before all bubbles stop flowing to prevent entry of water into
the BC.

RAPID EXHAUST VALVE (REV) DEFLATION
The Rapid Exhaust Valve, located within the upper (shoulder) unit of the Inflator, is connected to the
lower (power) inflator by a cable located inside the corrugated hose.
• It is actuated by grasping the lower inflator and pulling it down, away from your shoulder.
• The cable inside pulls the REV open, venting air from the BC through the vents of the upper unit.
• The amount of air vented depends on how far open the Exhaust Valve is (i.e., the distance you
pull the inner cable) and how long it is open.
• Short pulls vent small amounts of air for minor changes in buoyancy, and a long pull will vent the
entire BC in a matter of seconds.
• You retain just as much control over your buoyancy using the REV as with the manual deflate
button. You also get the benefit of eliminating water entry even if the Exhaust Valve remains open
after release of all the air.
